Automobile industry Electronics and telecommunications Security and lock technology Household appliances Hydromat® HW: for high flexibility, productivity and economy Pfiffner has been constructing special, highlydeveloped machinery for the manufacture of mass-produced workpieces since 1976. These electro-hydraulic, rotary transfer machines can be used for machining from bar stock, coil materials, or parts that are fed in automatically. An intelligent module system offers a high degree of flexibility: The construction and equipping of Pfiffner machines are essentially determined by the workpiece...

Fastening technology Fittings Hydraulics and pneumatics Gas and welding fitted with commercially available collet chucks of the W 25 type. This allows bar and profile materials of up to 25 mm in diameter and 100 mm in length to be machined without a problem. In spite of being clamped, the workpieces can be worked from both sides. A special turning unit takes out the individual parts and, after turning them through 180°, feeds them back into the chuck. There is no need for an additional removal unit on completion of the machining: the completed workpieces are automatically ejected between the last...

The consistent modular nature and flexibility of the mechanical systems are also reflected in the machine’s electrical control concept. The SIMATIC S7 from Siemens forms the basis of the machine control system. The integrated, Hydromat®-specific user screen facilitates the simple, dialogueled operation and programming of the machine. Repetitive machining tasks can be stored and called up again when needed, a feature which makes re-tooling much easier. In addition, the unified operating concept of all base machine models reduces training expenditure to a minimum. The machine’s control system concept...
